""Homo ergaster "" or "African "Homo erectus"" is an extinct chronospecies of "Homo" that lived in eastern and southern Africa during the early Pleistocene, between 1.8 million and 1.3 million years ago.
There is still disagreement on the subject of the classification, ancestry, and progeny of "H. ergaster", but it is now widely accepted to be the direct ancestor of later hominins, such as "Homo heidelbergensis", "Homo sapiens", and "Homo neanderthalensis" and Asian "Homo erectus".
It is one of the earliest members of the genus "Homo", possibly ancestral to, or sharing a common ancestor with, "Homo erectus". Some paleoanthropologists consider "H. ergaster" to be simply the African variety of "H. erectus"; this leads to the use of the term ""Homo erectus sensu stricto"" for the Asian "H. erectus", and ""Homo erectus sensu lato"" for the larger species comprising both the early African populations and the Asian populations.
The latest discoveries go even further claiming that all five contemporary species of early "Homo" in Africa, including "Homo habilis", "H. rudolfensis", "H. ergaster", and "H. erectus", are representatives from the same species, best named "H. erectus", which evolved about 2 million years ago in Africa and expanded through Eurasia, as far as China and Java, where it was first documented from about 1.2 million years ago.
The binomial name was published in 1975 by Groves and Mazák. The specific epithet, "ergaster", is derived from the Ancient Greek "workman", in reference to the comparatively advanced lithic technology developed by the species, introducing the Acheulean industry.

Human evolution is the evolutionary process that led to the emergence of anatomically modern humans. The topic typically focuses on the evolutionary history of the primates—in particular the genus Homo, and the emergence of Homo sapiens as a distinct species of the hominids (or great apes) rather than studying the earlier history that led to the primates. The study of human evolution involves many scientific disciplines, including physical anthropology, primatology, archaeology, paleontology, neurobiology, ethology, linguistics, evolutionary psychology, embryology and genetics. Genetic studies show that primates diverged from other mammals about 85 million years ago, in the Late Cretaceous period, and the earliest fossils appear in the Paleocene, around 55 million years ago. Within the Hominoidea (apes) superfamily, the Hominidae family diverged from the Hylobatidae (gibbon) family some 15–20 million years ago; African great apes (subfamily Homininae) diverged from orangutans (Ponginae) about 14 million years ago; the Hominini tribe (humans, Australopithecines and other extinct biped genera, and chimpanzees) parted from the Gorillini tribe (gorillas) between 9 million years ago and 8 million years ago; and, in turn, the subtribes Hominina (humans and biped ancestors) and Panina (chimps) separated about 7.5 million years ago to 5.6 million years ago.
The basic adaptation of the hominin line is bipedalism. The earliest bipedal hominin is considered to be either Sahelanthropus or Orrorin; alternatively, either Sahelanthropus or Orrorin may instead be the last shared ancestor between chimps and humans. Ardipithecus, a full biped, arose somewhat later, and the early bipeds eventually evolved into the australopithecines, and later into the genus Homo.
The earliest documented representative of the genus Homo is Homo habilis, which evolved around 2.8 million years ago, and is arguably the earliest species for which there is positive evidence of the use of stone tools. The brains of these early hominins were about the same size as that of a chimpanzee, although it has been suggested that this was the time in which the human SRGAP2 gene doubled, producing a more rapid wiring of the frontal cortex. During the next million years a process of rapid encephalization occurred, and with the arrival of Homo erectus and Homo ergaster in the fossil record, cranial capacity had doubled to 850 cm3. (Such an increase in human brain size is equivalent to each generation having 125,000 more neurons than their parents.) It is believed that Homo erectus and Homo ergaster were the first to use fire and complex tools, and were the first of the hominin line to leave Africa, spreading throughout Africa, Asia, and Europe between 1.3 to 1.8 million years ago.
According to the recent African origin of modern humans theory, modern humans evolved in Africa possibly from Homo heidelbergensis, Homo rhodesiensis or Homo antecessor and migrated out of the continent some 50,000 to 100,000 years ago, gradually replacing local populations of Homo erectus, Denisova hominins, Homo floresiensis and Homo neanderthalensis. Archaic Homo sapiens, the forerunner of anatomically modern humans, evolved in the Middle Paleolithic between 400,000 and 250,000 years ago. Recent DNA evidence suggests that several haplotypes of Neanderthal origin are present among all non-African populations, and Neanderthals and other hominins, such as Denisovans, may have contributed up to 6% of their genome to present-day humans, suggestive of a limited inter-breeding between these species. The transition to behavioral modernity with the development of symbolic culture, language, and specialized lithic technology happened around 50,000 years ago according to some anthropologists although others point to evidence that suggests that a gradual change in behavior took place over a longer time span.

10. Homo Heidelbergensis
The Homo Heidelbergensis lived in Europe and possibly Asia around 700,000 to 200,000 years ago. It was an early species of human that had a very large brow-ridge, and a distinctly larger braincase and a flatter face than those that came before them. This was the first early human that lived in colder climates. It is believed they were able to do so because of their shorter, wider bodies that helped to conserve heat. They were the first species that we know of that built shelters from wood and rocks, were adept at using fire, and routinely hunted large animals with wooden spears.
Workmen in Heidelberg in Germany first discovered them in 1908, which is where they got their name. Despite knowing a few details about how they lived based upon further discoveries that have been made, there’s still a lot that we don’t know. For example, is this just one species or the combination of a few unknown ones? Where does Homo Heidelbergensis fit in with our own evolutionary path? And, were there any other adaptations that made this species of human more suited to colder climates than their predecessors?
9. Homo Rudolfensis
The Homo Rudolfensis lived in Eastern Africa between 1.9 million and 1.7 million years ago. It was a very early species of human, and evidence of them is so rare that there’s only one example of a good fossil that was found in Kenya in 1986. The feature that makes the Homo Rudolfensis different is the size of the brain casing. In the example that has been found, it measures at 775 cubic centimeters, which is much larger than has been found in any specimens of earlier species, and signifies a much larger and capable brain. It also had a longer face and larger molar and premolar teeth that show its links to more recent types of human.
Because the fossil of Homo Rudolfensis comes from so long ago, we know very little about this species- we don’t even know if it comes from the same lineage as we do, or whether it was one that eventually died out through competition with more capable species. We also don’t know how large they grew, or even what differences, if any, that there were between the males and females.
8. Homo Habilis
Homo Habilis lived in Eastern and Southern Africa between 2.3 million and 1.4 million years ago, which makes them one of the longest surviving species of any of our ancestors. They are one of the earliest “Homo” species, and thought to be one of the first steps of evolution to what we are today. They had a larger brain case and smaller face and teeth than their predecessors, but still showed ape-like features such as longer arms and legs. They weighed about 70 pounds and would grow to be up to 5 feet tall.
The first confirmed fossil of Homo Habilis was discovered in 1960. The name Habilis means “Handy Man” in reference to the fact these are thought to be the first ones to use stone tools. Of course they lived an extremely long time ago so there’s a lot about them that we don’t know yet. Questions that researchers are dying to answer include; are they a direct ancestor of today’s humans? Are they related to, or the same species as Homo Rudolfensis? And, how did they survive the variable conditions on earth that we know went on at that time?
7. Homo Floresiensis
The Homo Floresiensis, often called the Hobbit, lived in Indonesia between 100,000 and 50,000 years ago. This is one of the most recently discovered species, having been found in 2003, and so far finds have been limited to the island of Flores. This was a very small species, a trait that is thought to have occurred because of island dwarfism where the limited resources available to creatures that are isolated on islands causes different evolutionary effects. They were only about 3 foot 6 inches tall, had very small brains, no chins, receding foreheads and very large feet. These estimates are based on a female skeleton that was found, that also suggests they could weigh up to 66 pounds.
The discovery of this species has raised more questions than it has answered for researchers. For example, stone tools that were found on the island date back over a million years, so who made them if Homo Floresiensis only arrived 100,000 years ago? How did they live, and why did they die out? And, most interestingly in regards to our own species, did they ever come into contact with our own predecessors?

Homo ergaster

Homo ergaster (meaning "working man") or African Homo erectus is an extinct chronospecies of the genus Homo that lived in eastern and southern Africa during the early Pleistocene, that is, between 1.9million and 1.4million years ago. It is one of the earliest hominins, which are those hominids that comprise the original members and species of the human clade after splitting from the line of the chimpanzees. (And Homo ergaster is variously thought to be ancestral to, or as sharing a common ancestor with, or as being the same species as,Homo erectus).

Interpreting Homo ergaster inevitably leads to Homo erectus, particularly regarding the taxonomy issues that persist within the scientific community of classifying the two species and separating their two lineages—if indeed they represent two separate lineages rather than one. Some palaeoanthropologists consider H. ergaster to be a variety of H. erectus, that is, the so-called African Homo erectus. Others call H. ergaster the direct ancestor of H. erectus, which then emigrated out of Africa into Eurasia and branched into a distinct species. Still others dispense with the specific epithet ergaster and make no such distinctions among fossils assigned to erectus.

Homo erectus

Homo erectus (meaning "upright man", from the Latin ērigere, "to put up, set upright") is an extinct species of hominid that lived throughout most of the Pleistocene geological epoch. Its earliest fossil evidence dates to 1.9 million years ago and the most recent to 70,000 years ago. It is generally thought that H. erectus originated in Africa and spread from there, migrating throughout Eurasia as far as Georgia, India, Sri Lanka, China and Indonesia. But other scientists posit that the species rose first, or separately, in Asia.

Debate also continues about the classification, ancestry, and progeny of Homo erectus, especially vis-à-vis Homo ergaster, with two major positions: 1) H. erectus is the same species as H. ergaster, and thereby H. erectus is a direct ancestor of the later hominins including Homo heidelbergensis, Homo neanderthalensis, and Homo sapiens; or, 2) it is in fact an Asian species distinct from African H. ergaster.

There is also another view—an alternative to 1): some palaeoanthropologists consider H. ergaster to be a variety, that is, the "African" variety, of H. erectus, and they offer the labels "Homo erectus sensu stricto" (strict sense) for the Asian species and "Homo erectus sensu lato" (broad sense) for the greater species comprising both Asian and African populations.

Homo habilis

A team led by scientists Louis and Mary Leakey uncovered the fossilized remains of a unique early human in the 1950s at Olduvai Gorge in Tanzania; these fossils were speculated to be a new species, and called Homo habilis ('handy man'), because they suspected that it was this slightly larger-brained early human that made the thousands of stone tools also found at Olduvai Gorge.

In its appearance and morphology, H. habilis is the least similar to modern humans of all species in the genus Homo (except the equally controversial H. rudolfensis), and its classification as Homo has been the subject of controversial debate since its first proposal in the 1960s.

Classification as Homo

There has been scholarly debate regarding its placement in the genus Homo rather than the genus Australopithecus. The small size and rather primitive attributes have led some experts (Richard Leakey among them) to propose excluding H. habilis from the genus Homo and placing them instead in Australopithecus as Australopithecus habilis.

The earth went from the Oligocene through the Miocene and into the Pliocene as it cooled into a series of ice ages. The Miocene boundaries are not marked by a single distinct global event but consist rather of regional boundaries between the warmer Oligocene and the cooler Pliocene.

The apes arose and diversified during the Miocene, becoming widespread in the Old World. By the end of this epoch, the ancestors of humans had split away from the ancestors of the chimpanzees to follow their own evolutionary path. As in the Oligocene before it, grasslands continued to expand and forests to dwindle in extent. In the Miocene seas, kelp forests made their first appearance and soon became one of Earth's most productive ecosystems.
The plants and animals of the Miocene were fairly modern. Mammals and birds were well-established. Whales, seals, and kelp spread. The Miocene is of particular interest to geologists and palaeoclimatologists as major phases of the Himalayan orogeny had occurred during the Miocene affecting monsoonal patterns in Asia, which were interlinked with glaciations in the northern hemisphere.

This was a very small species, a trait that is thought to have occurred because of island dwarfism where the limited resources available to creatures that are isolated on islands causes different evolutionary effects. They were only about 3 foot 6 inches tall, had very small brains, no chins, receding foreheads and very large feet. These estimates are based on a female skeleton that was found, that also suggests they could weigh up to 66 pounds.
The discovery of this species has raised more questions than it has answered for researchers. For example, stone tools that were found on the island date back over a million years, so who made them if Homo Floresiensis only arrived 100,000 years ago? How did they live, and why did they die out? And, most interestingly in regards to our own species, did they ever come into contact with our own predecessors?

Human Evolution - History of Humanity Documentary

Human ( Homo SapiensVersus Neaderthals) evolution is the evolutionary process leading to the appearance of anatomically modern humans. The topic typically focuses on the evolutionary history of the primates—in particular the genus Homo, and the emergence of Homo sapiens as a distinct species of the hominids (or "great apes")—rather than studying the earlier history that led to the primates. The study of human evolution involves many scientific disciplines, including physical anthropology, primatology, archaeology, paleontology, ethology, linguistics, evolutionary psychology, embryology and genetics.
Genetic studies show that primates diverged from other mammals about 85 million years ago, in the Late Cretaceous period, and the earliest fossils appear in the Paleocene, around 55 million years ago. Within the Hominoidea (apes) superfamily, the Hominidae family diverged from the Hylobatidae (gibbon) family some 15–20 million years ago; African great apes (subfamily Homininae) diverged from orangutans (Ponginae) about 14 million years ago; the Hominini tribe (humans, Australopithecines and other extinct biped genera, and chimpanzees) parted from the Gorillini tribe (gorillas) about 8 million years ago; and, in turn, the subtribes Hominina (humans and biped ancestors) and Panina (chimps) separated about 7.5 million years ago.
The basic adaptation of the hominin line is bipedalism. The earliest bipedal hominin is considered to be either Sahelanthropus or Orrorin; alternatively, either Sahelanthropus or Orrorin may instead be the last shared ancestor between chimps and humans. Ardipithecus, a full biped, arose somewhat later, and the early bipeds eventually evolved into the australopithecines, and later into the genus Homo.
The earliest documented representative of the genus Homo is Homo habilis, which evolved around 2.8 million years ago, and is arguably the earliest species for which there is positive evidence of the use of stone tools. The brains of these early hominins were about the same size as that of a chimpanzee, although it has been suggested that this was the time in which the human SRGAP2 gene doubled, producing a more rapid wiring of the frontal cortex. During the next million years a process of rapid encephalization occurred, and with the arrival of Homo erectus and Homo ergaster in the fossil record, cranial capacity had doubled to 850 cm3. (Such an increase in human brain size is equivalent to each generation having 125,000 more neurons than their parents.) It is believed that Homo erectus and Homo ergaster were the first to use fire and complex tools, and were the first of the hominin line to leave Africa, spreading throughout Africa, Asia, and Europe between 1.3 to 1.8 million years ago.
According to the recent African origin of modern humans theory, modern humans evolved in Africa possibly from Homo heidelbergensis, Homo rhodesiensis or Homo antecessor and migrated out of the continent some 50,000 to 100,000 years ago, gradually replacing local populations of Homo erectus, Denisova hominins, Homo floresiensis and Homo neanderthalensis. Archaic Homo sapiens, the forerunner of anatomically modern humans, evolved between 400,000 and 250,000 years ago. Recent DNA evidence suggests that several haplotypes of Neanderthal origin are present among all non-African populations, and Neanderthals and other hominins, such as Denisovans, may have contributed up to 6% of their genome to present-day humans, suggestive of a limited inter-breeding between these species. Anatomically modern humans evolved from archaic Homo sapiens in the Middle Paleolithic, about 200,000 years ago. The transition to behavioral modernity with the development of symbolic culture, language, and specialized lithic technology happened around 50,000 years ago according to many anthropologists although some suggest a gradual change in behavior over a longer time span.

Human Evolution: Crash Course Big History #6

In which John Green and Hank Green teach you about how human primates moved out of Africa and turned Earth into a real-life Planet of the Apes. And the apes are people! John and Hank teach you about how humans evolved, and the sort of tricks they picked up along the way like complex tool use, big brains, and fighting. Our ancestors adapted to the grasslands of Africa, and went through several iterations including Australopithecus, Homo Habilis, and Homo Ergaster/Erectus. Our ancestors tamed fire, made pressure flake tools, and eventually smartphones.

It is one of the earliest members of the genus "Homo", possibly ancestral to, or sharing a common ancestor with, "Homo erectus". Some paleoanthropologists consider "H. ergaster" to be simply the African variety of "H. erectus"; this leads to the use of the term ""Homo erectus sensu stricto"" for the Asian "H. erectus", and ""Homo erectus sensu lato"" for the larger species comprising both the early African populations and the Asian populations.
The latest discoveries go even further claiming that all five contemporary species of early "Homo" in Africa, including "Homo habilis", "H. rudolfensis", "H. ergaster", and "H. erectus", are representatives from the same species, best named "H. erectus", which evolved about 2 million years ago in Africa and expanded through Eurasia, as far as China and Java, where it was first documented from about 1.2 million years ago.
The binomial name was published in 1975 by Groves and Mazák. The specific epithet, "ergaster", is derived from the Ancient Greek "workman", in reference to the comparatively advanced lithic technology developed by the species, introducing the Acheulean industry.

Human evolution is the evolutionary process that led to the emergence of anatomically modern humans. The topic typically focuses on the evolutionary history of the primates—in particular the genus Homo, and the emergence of Homo sapiens as a distinct species of the hominids (or great apes) rather than studying the earlier history that led to the primates.

10. Homo Heidelbergensis
The Homo Heidelbergensis lived in Europe and possibly Asia around 700,000 to 200,000 years ago. It was an early species of human that had a very large brow-ridge, and a distinctly larger braincase and a flatter face than those that came before them. This was the first early human that lived in colder climates. It is believed they were able to do so because of their shorter, wider bodies that helped to conserve heat. They were the first species that we know of that built shelters from wood and rocks, were adept at using fire, and routinely hunted large animals with wooden spears.
Workmen in Heidelberg in Germany first discovered them in 1908, which is where they got their name. Despite knowing a few details about how they lived based upon further discoveries that have been made, there’s still a lot that we don’t know. For example, is this just one species or the combination of a few unknown ones? Where does Homo Heidelbergensis fit in with our own evolutionary path? And, were there any other adaptations that made this species of human more suited to colder climates than their predecessors?
9. Homo Rudolfensis
The Homo Rudolfensis lived in Eastern Africa between 1.9 million and 1.7 million years ago. It was a very early species of human, and evidence of them is so rare that there’s only one example of a good fossil that was found in Kenya in 1986. The feature that makes the Homo Rudolfensis different is the size of the brain casing. In the example that has been found, it measures at 775 cubic centimeters, which is much larger than has been found in any specimens of earlier species, and signifies a much larger and capable brain. It also had a longer face and larger molar and premolar teeth that show its links to more recent types of human.
Because the fossil of Homo Rudolfensis comes from so long ago, we know very little about this species- we don’t even know if it comes from the same lineage as we do, or whether it was one that eventually died out through competition with more capable species. We also don’t know how large they grew, or even what differences, if any, that there were between the males and females.
8. Homo Habilis
Homo Habilis lived in Eastern and Southern Africa between 2.3 million and 1.4 million years ago, which makes them one of the longest surviving species of any of our ancestors. They are one of the earliest “Homo” species, and thought to be one of the first steps of evolution to what we are today. They had a larger brain case and smaller face and teeth than their predecessors, but still showed ape-like features such as longer arms and legs. They weighed about 70 pounds and would grow to be up to 5 feet tall.
The first confirmed fossil of Homo Habilis was discovered in 1960. The name Habilis means “Handy Man” in reference to the fact these are thought to be the first ones to use stone tools. Of course they lived an extremely long time ago so there’s a lot about them that we don’t know yet. Questions that researchers are dying to answer include; are they a direct ancestor of today’s humans? Are they related to, or the same species as Homo Rudolfensis? And, how did they survive the variable conditions on earth that we know went on at that time?
7. Homo Floresiensis
The Homo Floresiensis, often called the Hobbit, lived in Indonesia between 100,000 and 50,000 years ago. This is one of the most recently discovered species, having been found in 2003, and so far finds have been limited to the island of Flores. This was a very small species, a trait that is thought to have occurred because of island dwarfism where the limited resources available to creatures that are isolated on islands causes different evolutionary effects. They were only about 3 foot 6 inches tall, had very small brains, no chins, receding foreheads and very large feet. These estimates are based on a female skeleton that was found, that also suggests they could weigh up to 66 pounds.
The discovery of this species has raised more questions than it has answered for researchers. For example, stone tools that were found on the island date back over a million years, so who made them if Homo Floresiensis only arrived 100,000 years ago? How did they live, and why did they die out? And, most interestingly in regards to our own species, did they ever come into contact with our own predecessors?

It also had a longer face and larger molar and premolar teeth that show its links to more recent types of human.
Because the fossil of Homo Rudolfensis comes from so long ago, we know very little about this species- we don’t even know if it comes from the same lineage as we do, or whether it was one that eventually died out through competition with more capable species. We also don’t know how large they grew, or even what differences, if any, that there were between the males and females.
8. Homo Habilis
Homo Habilis lived in Eastern and Southern Africa between 2.3 million and 1.4 million years ago, which makes them one of the longest surviving species of any of our ancestors. They are one of the earliest “Homo” species, and thought to be one of the first steps of evolution to what we are today. They had a larger brain case and smaller face and teeth than their predecessors, but still showed ape-like features such as longer arms and legs. They weighed about 70 pounds and would grow to be up to 5 feet tall.
The first confirmed fossil of Homo Habilis was discovered in 1960. The name Habilis means “Handy Man” in reference to the fact these are thought to be the first ones to use stone tools. Of course they lived an extremely long time ago so there’s a lot about them that we don’t know yet. Questions that researchers are dying to answer include; are they a direct ancestor of today’s humans? Are they related to, or the same species as Homo Rudolfensis? And, how did they survive the variable conditions on earth that we know went on at that time?
7. Homo Floresiensis
The Homo Floresiensis, often called the Hobbit, lived in Indonesia between 100,000 and 50,000 years ago. This is one of the most recently discovered species, having been found in 2003, and so far finds have been limited to the island of Flores. This was a very small species, a trait that is thought to have occurred because of island dwarfism where the limited resources available to creatures that are isolated on islands causes different evolutionary effects. They were only about 3 foot 6 inches tall, had very small brains, no chins, receding foreheads and very large feet. These estimates are based on a female skeleton that was found, that also suggests they could weigh up to 66 pounds.
The discovery of this species has raised more questions than it has answered for researchers. For example, stone tools that were found on the island date back over a million years, so who made them if Homo Floresiensis only arrived 100,000 years ago? How did they live, and why did they die out? And, most interestingly in regards to our own species, did they ever come into contact with our own predecessors?

Human ( Homo SapiensVersus Neaderthals) evolution is the evolutionary process leading to the appearance of anatomically modern humans. The topic typically focuses on the evolutionary history of the primates—in particular the genus Homo, and the emergence of Homo sapiens as a distinct species of the hominids (or "great apes")—rather than studying the earlier history that led to the primates. The study of human evolution involves many scientific disciplines, including physical anthropology, primatology, archaeology, paleontology, ethology, linguistics, evolutionary psychology, embryology and genetics.
Genetic studies show that primates diverged from other mammals about 85 million years ago, in the Late Cretaceous period, and the earliest fossils appear in the Paleocene, around 55 million years ago. Within the Hominoidea (apes) superfamily, the Hominidae family diverged from the Hylobatidae (gibbon) family some 15–20 million years ago; African great apes (subfamily Homininae) diverged from orangutans (Ponginae) about 14 million years ago; the Hominini tribe (humans, Australopithecines and other extinct biped genera, and chimpanzees) parted from the Gorillini tribe (gorillas) about 8 million years ago; and, in turn, the subtribes Hominina (humans and biped ancestors) and Panina (chimps) separated about 7.5 million years ago.
The basic adaptation of the hominin line is bipedalism. The earliest bipedal hominin is considered to be either Sahelanthropus or Orrorin; alternatively, either Sahelanthropus or Orrorin may instead be the last shared ancestor between chimps and humans. Ardipithecus, a full biped, arose somewhat later, and the early bipeds eventually evolved into the australopithecines, and later into the genus Homo.
The earliest documented representative of the genus Homo is Homo habilis, which evolved around 2.8 million years ago, and is arguably the earliest species for which there is positive evidence of the use of stone tools. The brains of these early hominins were about the same size as that of a chimpanzee, although it has been suggested that this was the time in which the human SRGAP2 gene doubled, producing a more rapid wiring of the frontal cortex. During the next million years a process of rapid encephalization occurred, and with the arrival of Homo erectus and Homo ergaster in the fossil record, cranial capacity had doubled to 850 cm3. (Such an increase in human brain size is equivalent to each generation having 125,000 more neurons than their parents.) It is believed that Homo erectus and Homo ergaster were the first to use fire and complex tools, and were the first of the hominin line to leave Africa, spreading throughout Africa, Asia, and Europe between 1.3 to 1.8 million years ago.
According to the recent African origin of modern humans theory, modern humans evolved in Africa possibly from Homo heidelbergensis, Homo rhodesiensis or Homo antecessor and migrated out of the continent some 50,000 to 100,000 years ago, gradually replacing local populations of Homo erectus, Denisova hominins, Homo floresiensis and Homo neanderthalensis. Archaic Homo sapiens, the forerunner of anatomically modern humans, evolved between 400,000 and 250,000 years ago. Recent DNA evidence suggests that several haplotypes of Neanderthal origin are present among all non-African populations, and Neanderthals and other hominins, such as Denisovans, may have contributed up to 6% of their genome to present-day humans, suggestive of a limited inter-breeding between these species. Anatomically modern humans evolved from archaic Homo sapiens in the Middle Paleolithic, about 200,000 years ago. The transition to behavioral modernity with the development of symbolic culture, language, and specialized lithic technology happened around 50,000 years ago according to many anthropologists although some suggest a gradual change in behavior over a longer time span.

homo ergaster

Homo ergaster or African Homo erectus is an extinct chronospecies of Homo that lived in eastern and southern Africa during the early Pleistocene, between 1.8 million and 1.3 million years ago. Wikipedia

Origins of Genus Homo–Australopiths and Early Homo; Variation of Early Homo; Speciation of Homo

(Visit: http://www.uctv.tv/) This symposium explores evidence bearing on the emergence of our genus, focusing on possible antecedents to Homo, changes in diet and body form as Australopithecus evolved toward Homo, ancient species within the genus, and evolutionary processes likely operating 2.5 - 1.5 million years ago. Recorded on 02/05/2016. Series: "CARTA - Center for AcademicResearch and Training in Anthropogeny" [4/2016] [Science] [Show ID: 30634]

Homo ergaster - Video Learning - WizScience.com

""Homo ergaster "" or "African "Homo erectus"" is an extinct chronospecies of "Homo" that lived in eastern and southern Africa during the early Pleistocene, between 1.8 million and 1.3 million years ago.
There is still disagreement on the subject of the classification, ancestry, and progeny of "H. ergaster", but it is now widely accepted to be the direct ancestor of later hominins, such as "Homo heidelbergensis", "Homo sapiens", and "Homo neanderthalensis" and Asian "Homo erectus".
It is one of the earliest members of the genus "Homo", possibly ancestral to, or sharing a common ancestor with, "Homo erectus". Some paleoanthropologists consider "H. ergaster" to be simply the African variety of "H. erectus"; this leads to the use of the term ""Homo erectus sensu stricto"" for the Asian "H. erectus", and ""Homo erectus sensu lato"" for the larger species comprising both the early African populations and the Asian populations.
The latest discoveries go even further claiming that all five contemporary species of early "Homo" in Africa, including "Homo habilis", "H. rudolfensis", "H. ergaster", and "H. erectus", are representatives from the same species, best named "H. erectus", which evolved about 2 million years ago in Africa and expanded through Eurasia, as far as China and Java, where it was first documented from about 1.2 million years ago.
The binomial name was published in 1975 by Groves and Mazák. The specific epithet, "ergaster", is derived from the Ancient Greek "workman", in reference to the comparatively advanced lithic technology developed by the species, introducing the Acheulean industry.

Human Evolution - Documentary

Human evolution is the evolutionary process that led to the emergence of anatomically modern humans. The topic typically focuses on the evolutionary history of the primates—in particular the genus Homo, and the emergence of Homo sapiens as a distinct species of the hominids (or great apes) rather than studying the earlier history that led to the primates. The study of human evolution involves many scientific disciplines, including physical anthropology, primatology, archaeology, paleontology, neurobiology, ethology, linguistics, evolutionary psychology, embryology and genetics. Genetic studies show that primates diverged from other mammals about 85 million years ago, in the Late Cretaceous period, and the earliest fossils appear in the Paleocene, around 55 million years ago. Within the Hominoidea (apes) superfamily, the Hominidae family diverged from the Hylobatidae (gibbon) family some 15–20 million years ago; African great apes (subfamily Homininae) diverged from orangutans (Ponginae) about 14 million years ago; the Hominini tribe (humans, Australopithecines and other extinct biped genera, and chimpanzees) parted from the Gorillini tribe (gorillas) between 9 million years ago and 8 million years ago; and, in turn, the subtribes Hominina (humans and biped ancestors) and Panina (chimps) separated about 7.5 million years ago to 5.6 million years ago.
The basic adaptation of the hominin line is bipedalism. The earliest bipedal hominin is considered to be either Sahelanthropus or Orrorin; alternatively, either Sahelanthropus or Orrorin may instead be the last shared ancestor between chimps and humans. Ardipithecus, a full biped, arose somewhat later, and the early bipeds eventually evolved into the australopithecines, and later into the genus Homo.

During the next million years a process of rapid encephalization occurred, and with the arrival of Homo erectus and Homo ergaster in the fossil record, cranial capacity had doubled to 850 cm3.

It is believed that Homo erectus and Homo ergaster were the first to use fire and complex tools, and were the first of the hominin line to leave Africa, spreading throughout Africa, Asia, and Europe between 1.3 to 1.8 million years ago.

10. Homo Heidelbergensis
The Homo Heidelbergensis lived in Europe and possibly Asia around 700,000 to 200,000 years ago. It was an early species of human that had a very large brow-ridge, and a distinctly larger braincase and a flatter face than those that came before them. This was the first early human that lived in colder climates. It is believed they were able to do so because of their shorter, wider bodies that helped to conserve heat. They were the first species that we know of that built shelters from wood and rocks, were adept at using fire, and routinely hunted large animals with wooden spears.
Workmen in Heidelberg in Germany first discovered them in 1908, which is where they got their name. Despite knowing a few details about how they lived based upon further discoveries that have been made, there’s still a lot that we don’t know. For example, is this just one species or the combination of a few unknown ones? Where does Homo Heidelbergensis fit in with our own evolutionary path? And, were there any other adaptations that made this species of human more suited to colder climates than their predecessors?
9. Homo Rudolfensis
The Homo Rudolfensis lived in Eastern Africa between 1.9 million and 1.7 million years ago. It was a very early species of human, and evidence of them is so rare that there’s only one example of a good fossil that was found in Kenya in 1986. The feature that makes the Homo Rudolfensis different is the size of the brain casing. In the example that has been found, it measures at 775 cubic centimeters, which is much larger than has been found in any specimens of earlier species, and signifies a much larger and capable brain. It also had a longer face and larger molar and premolar teeth that show its links to more recent types of human.
Because the fossil of Homo Rudolfensis comes from so long ago, we know very little about this species- we don’t even know if it comes from the same lineage as we do, or whether it was one that eventually died out through competition with more capable species. We also don’t know how large they grew, or even what differences, if any, that there were between the males and females.
8. Homo Habilis
Homo Habilis lived in Eastern and Southern Africa between 2.3 million and 1.4 million years ago, which makes them one of the longest surviving species of any of our ancestors. They are one of the earliest “Homo” species, and thought to be one of the first steps of evolution to what we are today. They had a larger brain case and smaller face and teeth than their predecessors, but still showed ape-like features such as longer arms and legs. They weighed about 70 pounds and would grow to be up to 5 feet tall.
The first confirmed fossil of Homo Habilis was discovered in 1960. The name Habilis means “Handy Man” in reference to the fact these are thought to be the first ones to use stone tools. Of course they lived an extremely long time ago so there’s a lot about them that we don’t know yet. Questions that researchers are dying to answer include; are they a direct ancestor of today’s humans? Are they related to, or the same species as Homo Rudolfensis? And, how did they survive the variable conditions on earth that we know went on at that time?
7. Homo Floresiensis
The Homo Floresiensis, often called the Hobbit, lived in Indonesia between 100,000 and 50,000 years ago. This is one of the most recently discovered species, having been found in 2003, and so far finds have been limited to the island of Flores. This was a very small species, a trait that is thought to have occurred because of island dwarfism where the limited resources available to creatures that are isolated on islands causes different evolutionary effects. They were only about 3 foot 6 inches tall, had very small brains, no chins, receding foreheads and very large feet. These estimates are based on a female skeleton that was found, that also suggests they could weigh up to 66 pounds.
The discovery of this species has raised more questions than it has answered for researchers. For example, stone tools that were found on the island date back over a million years, so who made them if Homo Floresiensis only arrived 100,000 years ago? How did they live, and why did they die out? And, most interestingly in regards to our own species, did they ever come into contact with our own predecessors?
